TWL: RE: Wire gauge

As one who wants to avoid 120VAC and rely as much as possible on 12VDC
directly from the batteries, when I first saw the original post, I wondered
why not forget the inverter, get a 12VDC TV and a 12VDC DVD player? To me
there seems to be too much of a power loss in using an inverter to convert
12VDC to 120VAC, and then converting that back down into an appliance that
is basicly a DC device anyway.

Same goes for laptop PC's.

Is there something I'm missing. Why should you use a 120VAC device when
there is a 12VDC alternative?

Thanks to all who responded to my question about the proper gauge wire to
connect my 300w inverter.  I think I'll go with the 10 gauge wire to help
insure against voltage drop in a hot engine room environment, and just in
case
the run is longer than I estimate.

Maybe this is how it starts... a small inverter so we can watch TV quietly.
Then we start adding more batteries, then a bigger inverter, a bigger
alternator, and so on.  ;-)

Jim:
You didn't miss anything. That's the way we've done it for years, but it
does limit your choices. There are relatively few dc devices on the
market.
